Chickpeas - disease management, MRZ Mid North locations
Aims
  • .To evaluate ascochyta blight (AB) response of new advanced varieties by comparing their susceptibility to commercial varieties
Key messages
  • Environmental conditions of wet weather favoured AB disease development and allowed for evaluation of virulence of disease and susceptibility of different chickpea varieties/lines.
  • The current trial established a change in susceptibility of AB pathogen in varieties previously rated as moderately resistant and resistant. This result indicates that there has been a change in virulence in the AB pathogen in chickpeas across SA. Consequently, this has resulted in all chickpea resistance ratings being revised to susceptible or moderately susceptible in the southern region.
  • Application of fortnightly foliar sprays with Chlorothalonil at the registered rate of 2 L/ha ahead of rain effectively controlled AB pathogen and benefited yields similarly across all varieties irrespective of their AB category. A cost benefit analysis of this continuous protection was not carried out in the current trial and therefore the profitability of this strategy will require further evaluation.
  • The current trial identified advanced breeding lines with improved level of AB resistance over the current commercial varieties such as Genesis™ 090 and PBA Slasher which are rated as being moderately resistant. These advanced breeding lines will be evaluated further and developed through our collaboration with Pulse Breeding Australia.
  • Overall, chickpea production in the southern region will require close monitoring of disease together with adapting an integrated disease management strategy that incorporates agronomic practices including use of AB free seed, variety selection, use of thiram-based seed treatments and multiple foliar fungicides, maintaining adequate crop rotations with non-host crops and maintaining adequate distance from previous chickpea crops.
